Abstract

A process for the catalytic transformation of SO2-poor gases to obtain SO3 and/or sulfuric acid, by intermediate absorption of the SO3 formed in the first phase and preheating of the SO2 gases to be used, in thermal permutation with the hot SO3 gases, characterized in that the intermediate absorption of the SO3 of the gases leaving the first reaction phase is carried out at a temperature of 170 to 250º C, preferably of around 200º C, and because the SO3 gases of the first phase of the reaction, before being subjected to intermediate absorption, they are cooled in a first phase of thermal permutation with the gases released from the SO3 of the first phase of the reaction and then, in a second phase of thermal permutation, with the incoming SO2 gas, not preheated, whose SO2 concentration is less than 9%, preferably around 6%, at a temperature that corresponds approximately to the operating temperature or intermediate absorption.
